wifi: ath11k: fix wrong handling of CCMP256 and GCMP ciphers
Currently for CCMP256, GCMP128 and GCMP256 ciphers, in ath11k_install_key() IEEE80211_KEY_FLAG_GENERATE_IV_MGMT is not set. And in ath11k_mac_mgmt_tx_wmi() a length of IEEE80211_CCMP_MIC_LEN is reserved for all ciphers. This results in unexpected management frame drop in case either of above 3 ciphers is used. The reason is, without IEEE80211_KEY_FLAG_GENERATE_IV_MGMT set, mac80211 will not generate CCMP/GCMP headers in frame for ath11k. Also MIC length reserved is wrong. Such frame is dropped later by hardware: ath11k_pci 0000:5a:00.0: mac tx mgmt frame, buf id 0 ath11k_pci 0000:5a:00.0: mgmt tx compl ev pdev_id 1, desc_id 0, status 1 From user point of view, we have observed very low throughput due to this issue: action frames are all dropped so ADDBA response from DUT never reaches AP. AP can not use aggregation thus throughput is low. Fix this by setting IEEE80211_KEY_FLAG_GENERATE_IV_MGMT flag and by reserving proper MIC length for those ciphers.
